【问题描述】:
请注意,我已经查看了以下来源:
How do I run Selenium in Xvfb?
这并没有解决我的问题。
我正在使用:
- Python 2.7
- 硒 3.0.2
- xvfbwrapper 0.2.9
- PyVirtualDisplay 0.2.1
在 Mac OSX El Capitan (10.11.6 (15G1108)) 上运行
我收到以下错误(与上述链接中的错误相同):
Traceback (most recent call last):
File "/Users/user/Desktop/test.py", line 50, in <module>
display = Display(visible=0, size=(800, 600))
File "/Library/Python/2.7/site-packages/pyvirtualdisplay/display.py", line 34, in __init__
self._obj = self.display_class(
File "/Library/Python/2.7/site-packages/pyvirtualdisplay/display.py", line 52, in display_class
cls.check_installed()
File "/Library/Python/2.7/site-packages/pyvirtualdisplay/xvfb.py", line 38, in check_installed
ubuntu_package=PACKAGE).check_installed()
File "/Library/Python/2.7/site-packages/easyprocess/__init__.py", line 180, in check_installed
raise EasyProcessCheckInstalledError(self)
EasyProcessCheckInstalledError: cmd=['Xvfb', '-help']
OSError=[Errno 2] No such file or directory
Program install error!
我知道我也安装了 Xvfb:
Xvfb -help
use: X [:<display>] [option]
-a # default pointer acceleration (factor)
-ac disable access control restrictions
-audit int set audit trail level
-auth file select authorization file
-br create root window with black background
+bs enable any backing store support
-bs disable any backing store support
-c turns off key-click
...
-pixdepths list-of-int support given pixmap depths
+/-render turn on/off RENDER extension support(default on)
-linebias n adjust thin line pixelization
-blackpixel n pixel value for black
-whitepixel n pixel value for white
-fbdir directory put framebuffers in mmap'ed files in directory
-shmem put framebuffers in shared memory
如果 pip 安装在不同的目录中寻找 xvfb,一些关于如何重定向它正在寻找的位置的指导将不胜感激。
这是我的代码:
from easyprocess import EasyProcess
from pyvirtualdisplay import Display
from selenium import webdriver
display = Display(visible=0, size=(800, 600))
display.start()
# now Firefox will run in a virtual display.
# you will not see the browser.
browser = webdriver.Firefox()
browser.get('http://www.google.com')
print browser.title
browser.quit()
display.stop()
我已经进行了无数的 pip 安装和谷歌搜索,但到目前为止没有任何帮助,最终目标是拥有能够处理下载的无头自动化,这是 PhantomJS 无法做到的。对该主题的任何帮助也将不胜感激。
【问题讨论】:
-
你不能在 osx 上使用它
-
@CoreyGoldberg 我能用什么?我投奔了 casperjs,但如果我想使用 python,如何在 OSX 上无头运行它?
-
Chrome 刚刚发布了 59+ 版本的无头版本。你可以看看这个。
